(C2. 99--257) Theinvention relates co a pickle syringe of the kind serving to injectpickle into meat for purposes of preservaden, tl1e said syringeconsisting of a, piston cylinder reg istering at its end With .a heavy,hollow needle ha.ving lateral discharge holes.

In tl1e known syringes cf this kind tl1e needle is at first introducedinto the rneat, after Which the piston is pnsned forward by means of ahandle provided on its rearwardly projecting piston rod, whereby theliquid in front of the piston is forced through tl1e front end wall ofthe cylinder into tl1e needle, hence to be distributed thrcugh thelateral holes providecl in same into the rneat. When the piston iswithclrawn a fresh portion of pickle is sucl ed into tl1e cylinderthrougl1 a nen-return valve provided in the freut end of the -cylinder.

"Ehe object cf the present invention is to facilitate the operation cftl1e pickle syringe so that the said handle is fully dispensed with.

For this qnur.pose the inlet end f tl1e needle is according to theinvention attached t0 the nisten of tne cylindsr. As a result, tl1eneedle moves with the piston in relnlicn to tl1e cylinder.

Both the introcluciion of tl1e needle into the meat and tl1e injection0f the pickle take place in one uniform movement. As this operationproceeds and tne needle encounters greater resistance the conveyance ofthe pickle is increased.

In accordance witl1 the invention such part of the needle as extenclsoutside the cylinder may be provided with a stop collar to limit thepiston stroke.

In accsrclance with the invention there rnay further be provicled apressure spring behind tl1e piston. Only wlxen the needle uns -beenintroduced into the meat and the stop collar is brought to rast againstthe outer side cf the meat, the conveyance of tne pickle Will begin, thespring having in all essentials prevented ehe movenent or" the piston sofar.

When the cylinder is wiihclrawn, the spring will at first recover itsoriginal sl1ape and a fresh supply cf pickle is simultaneously su-ekedinto the cylinder, and then tl1e needle will be withdrawn frorn the meatwo.

The syringe :can be operated by one hand.

Tlre dra.wing shows an embodiment of a pickle syringe in accordance withthe invantion.

FIGURE 1 shows the syringe, ready to be used, and partially in section.

FEGURE 2 is the sarne, after tl1e needle has been introcluced into ihen1eat and the pickle injected.

From an elevated tank (not shown) pickle may flow into the cylinder 1 ofthe syringe through a nipple 2 provicled in the raar end Wall 3 in whichis inserted a non-return valve 4. Between the end Wall 3 and the piston5 of the syringe is inserted a powerful helical pressure spring 6 urgingthe piston 5 into the position shown in FIGURE 1.

lnside the piston is =provlcled another nomreturn valve 7 which-communicates witl1 tlre central passage S in a heavy needle 9 in thefront part of which, that is, in freut 0f a stop collar 11 that isprovided witl1 an ad- }usment screw Tal); there are lateral holes 12communicating With the passage 8. The needle is passed through anozherend cover 13 of the syringe, laut this assage need not be liquid-tight.

When operated the syringe Witl1 the needle 9 is passed into tne rncat(not shown) until the stop collar 11 is brougnt irrte contact with thesurface cf the meat. Up to this anornent the spring 6 has prevented thepiston 5 -rom rncving inside the cylinder ll. When tl1e cylinder 1 issubsequently passecl further towards the meat surface by band, thespring 6 will be compressecl and the portion of =picl le contained inths chamber 14 of tl1e cylinder will be forced into tl1e neeclle throughtl1e valve 7 and be injected through the l1oles 12 into the meat.

At Ehe close of this movement the syringe is in the position indicatedin FIGURE 2 and when the syringe is subsequently withdrawn, alle spring6 Will at first recover its original sl1ape by which a fresh portion ofpickle is drawn through tl1e nipple 2 into the charnber 14, and onlyx-vhen the needle 9 has been pressed entirely out of the cylinder 1 theneealle will be drawn clear cf the meat -by the continued wit'ndrawal 0fthe cylinder.

l1e pickle syringe according to the invention may also be 0f otl1erdesigns than that disclosed. Tims, the nonreturn valve 4 may be disposedin t-he rear art cf the cylindrical Wall, just as cl1e spring 6 and thestop collar 11 eacl1 scparately or bc-t'n may lse dispensed With or besubstituted by other elements having a corresponcling eifect.

What 1 claim and desire t0 secure by Letters Patent is:

1. A syringe for injecting, a preserving fluid into meat comprising, ahollow closed-end cylinder forzning a piston cham=ber an inlet openingin one end of the cylinder and check valve therefor openanle undersuction in tl1e charnb-er to admit fluid through the inlet opening intotlre chamber, the other end of tne cylinder having a nneclleopeningihereihraugl1, a hollow neeclle having lateral discharge holes slidablymounted in the neeclleopening, a piston slidable -within the -chan1berand comnected to the hollow needle, the piston having an openingtherethrough corn.municating With tl1e hollow needle, a check valve inthe piston opening operable under pressure in tl1e chamber t0 adrnitfluid from tl1e chamber to the =l10llow needle, and a spring interposedbetween tl1e pisston and the end of the cylinder having the inletcpening.

2. A syringe for injecting a preserving i'luid into meat as claimecl inclaixn 1, wherein there is a stop collar on the needle outside thecylinder.

3. A syringe f0r injeciing a preserving fiuid into meat as cla.imed inclaim 2 wherein the stop collar is adjustable along tl1e hollsw needle.
